Title: Sub procedures
A sub procedure is a group of reusable code which can be called anywhere in your program. This eliminates the need of writing the same code over and over again. This enables the programmers to divide a big program into a number of small and manageable sub procedures. Sub procedures don’t return any values.
We declared two sub procedures: ShowMessage() and MySum(). Next they were called in the sub procedure Button1_Click()
Type and check the code above.
